My invent on consists in animprovement 1n thread protectors for the threaded ends of PiPQSftllblDg, rods, etc and hasv for its object to provide a-simple, cheapqand easily adjusted device which may be directly' inserted by pushing over. the end of the pipe or other article andthenif desired, par. tially turned to bind it in position by en gage'ment with the threads, to holdit in place untilfifor'cibly removed.

Figs; 3 and 4 are detail views'showing modifica- Lions Fig. 5 is a-view in elevation showing the device applied to the endv of a tube and illustrating thespiral arrangement of the tongues. j

The protector is formed of aband-Q of sheet metal in circular form, connected together by rivets as shown, or in any other suitable way, preferably having aterminal flange 3 adapted to cover the end or a portion of the end of the pipe or other article.

when in position, as indicated in Fig. 2.

For the purpose ,of providing locking devices for engagement with the-threads of the protected article, the body portion of the ring is partially cut or slottedthrough as at 4 and elongated tongues 5v are. provided,

having their terminals Ghent inwardly, as

Y indicated in Fig. 1, said tongue terminals constituting rearwardly extending resilient elements adapted to interlock with the threads. e

Upon inserting the protector over the end of the article it is pushed directly thereon, .the terminals 6 of tongues 5 springing over each successive thread and downwardly into the recesses between adjacent threads, until the flange 3 makes contact or until no more THREADFrRQTECrQR." f"

Fig.3, orthe tongues 5. may extendlongn tudina-lly ofthe ring QX and have its end deit is desired to. remove the device, this may readily be doneby merely un-screwing' it a few times to release the tongues-from en-v gagement, and the device maythen be discarded, or if desired may be used over again-..

'Itwill be understood "that any desired number of the tongues maybe employedand that informing them from the blank, their terminals may be located to approx? mate the spiral arrangement ofthe threads so that all of the tongue-terminals will be in .engageinent, thereby insuring the devicein Various forms of the resilient tongues of rmg 2 may be 'employed, of partly circular with deflected terminals 6: as m vflcoted to' alinesvith thethreadsby its'in- \var'dly turned terminal 6" as in F ig. 4/

With either of the various constructions the terminals may have rounded or arched edges for engagement with the teeth, as desired, to suit diiieren't conditions of use.

.As thus applied, the shell or body portion of the protector completely inclosesthe entire length of threads "and envelops and modified in different details, but all such:

2. Athread protector consisting of a ring of sheet metal having inwardly'extending spring abutments adapted to move radially with relation to the axial center of the ring". 3. A'thread protector consisting of a ring I of sheet metal provided with inwardly extending spring abutments having freely movable terminals adjacent to the outer end of the ring to pass over the threads in applyin the protector thereto. i

4. K thread protector consisting of a ring of sheet metal having inwardly extending freely resilient abutments adapted to spring overand engage against the threads, and a terminal inwardly extending flange.

5. A thread protector consisting of a ring of sheet metal having one or more elongated elastic tongues partially severed from the metal and bent inwardly beyond the in ner face of the ring.

6. A thread protector consisting of a ring,

of sheet metal having a plurality of resilient tongues partially severed from the metal and bent inward-lybeyond the inner face of the ring, said tongues having their termihills located inspiral arrangement to conform to the spiral of a thread.
